A Novel Resolver-to-360° Linearized Converter
(
IEEE
, 2004 , Article)
A novel and simple resolver-to-dc converter is presented. It is shown that by appropriate processing of the sine and cosine resolver signals, the proposed converter may produce an output voltage proportional to the shaft ...
A high precision resolver-to-DC converter
(
IEEE
, 2005 , Article)
A newly developed resolver converter, providing a pseudolinear voltage proportional to the shaft angle, is presented. This converter is based on a new concept involving the absolute values of the demodulated sine and cosine ...
A novel method for estimating the angle from analog co-sinusoidal quadrature signals
(
Elsevier
, 2008 , Article)
The paper presents a new low cost and accurate method for determining the angle from sine and cosine signals produced by resolvers and sinusoidal encoders. In the proposed scheme, multiple phase-shifted sinusoids (PSS) are ...
A novel multilevel carrier-based PWM-control method for GTO inverter in low index modulation region
(
IEEE
, 2006 , Article)
Gate turn offs (GTOs) have an inherent minimum ON-OFF time, which is needed for their safe operation. For GTO-based three-level or neutral-point-clamped (NPC) inverters, this minimum ON-OFF pulsewidth limitation results ...
الحماية المدنية للعلامة التجارية غير المسجلة في الأردن : دراسة تحليلية نقدية للمادة 34 من قانون العلامات التجارية الأردني
(
جامعة مؤتة
, 2009 , Article)
يتضمن هذا البحث, دراسة تحليلية نقدية للمادة 34 من قانون العلامات التجارية الأردني التي نصت على أنه: "لا يحق لأحد أن يقيم دعوى بطلب تعويضات عن أي تعد على علامة تجارية غير مسجلة في المملكة الأردنية الهاشمية إلا أنه يحق له ...
ترقين العلامة التجارية في القانون الأردني
(
مجلس النشر العلمي - جامعة الكويت
, 2009 , Article)
إذا كان من المسلم به، أن الحق في العلامة التجارية، يكتسب بوسيلتين اثنتين لا ثالث لهما؛ الأولى: الاستعمال، والثانية: التسجيل، فإنه- أي الحق في العلامة التجارية- ينقضي لغير سبب، البعض منها محل تسليم والآخر محل نظر. لذلك، ...
Role of catalyst type in the selective separation of olefinic and paraffinic hydrocarbons using xerogel-based adsorbents
(
Elsevier
, 2008 , Article)
Resorcinol-Formaldehyde (RF)-based activated carbon xerogels are typically synthesized using a homogeneous, sodium-based, catalyst solution. In this work, the synthesis of RF-based carbon xerogels using other, non-typical, ...
A cascade of artificial neural networks to predict transformers oil parameters
(2009 , Article)
In this paper artificial neural networks have been constructed to predict different transformers oil parameters. The prediction is performed through modeling the relationship between the insulation resistance measured ...
A semantic approach for document clustering
(
Academy Publisher
, 2009 , Article)
Conventional document mining systems mainly use the presence or absence of keywords to mine texts. However, simple word counting and frequency distributions of term appearances do not capture the meaning behind the words, ...
Quality assurance considerations in chemical analysis
(
John Wiley & Sons, Ltd.
, 2009 , Article)
Quality Assurance (QA) for an analytical laboratory is an essential tool to ensure good comparability of data. In order to achieve this purpose, processes are monitored and performance problems are systematically solved. ...
